TigerBeetle is a financial transactions database designed for mission critical safety and performance to power the next 30 years of OLTP.

First, download a prebuilt copy of TigerBeetle.

# macOS
curl -Lo tigerbeetle.zip https://mac.tigerbeetle.com && unzip tigerbeetle.zip && ./tigerbeetle version

# Linux
curl -Lo tigerbeetle.zip https://linux.tigerbeetle.com && unzip tigerbeetle.zip && ./tigerbeetle version

# Windows
powershell -command "curl.exe -Lo tigerbeetle.zip https://windows.tigerbeetle.com; Expand-Archive tigerbeetle.zip .; .\tigerbeetle version"

Want to build from source locally?

git clone https://github.com/tigerbeetle/tigerbeetle && cd tigerbeetle
./scripts/install_zig.sh # or .bat if you're on Windows.
zig/zig build
./tigerbeetle version

Then create the TigerBeetle data file.

./tigerbeetle format --cluster=0 --replica=0 --replica-count=1 0_0.tigerbeetle

info(io): creating "0_0.tigerbeetle"...
info(io): allocating 660.140625MiB...

And start the replica.

./tigerbeetle start --addresses=3000 --development 0_0.tigerbeetle

info(io): opening "0_0.tigerbeetle"...
info(main): 0: cluster=0: listening on 127.0.0.1:3000

Now that you've got a cluster running, let's connect to it and do some accounting!

First let's create two accounts. (Don't worry about the details, you can read about them later.)

./tigerbeetle repl --cluster=0 --addresses=3000

  Hit enter after a semicolon to run a command.

Examples:
  create_accounts id=1 code=10 ledger=700 flags=linked|history,
                  id=2 code=10 ledger=700;
  create_transfers id=1 debit_account_id=1 credit_account_id=2 amount=10 ledger=700 code=10;
  lookup_accounts id=1;
  lookup_accounts id=1, id=2;
  get_account_transfers account_id=1 flags=debits|credits;
  get_account_balances account_id=1 flags=debits|credits;

create_accounts id=1 code=10 ledger=700,
                id=2 code=10 ledger=700;

Now create a transfer of 10 (of some amount/currency) between the two accounts.

create_transfers id=1 debit_account_id=1 credit_account_id=2 amount=10 ledger=700 code=10;

Now, the amount of 10 has been credited to account 2 and debited from account 1. Let's query TigerBeetle for these two accounts to verify!

lookup_accounts id=1, id=2;

{
  "id": "1",
  "user_data": "0",
  "ledger": "700",
  "code": "10",
  "flags": "",
  "debits_pending": "0",
  "debits_posted": "10",
  "credits_pending": "0",
  "credits_posted": "0"
}
{
  "id": "2",
  "user_data": "0",
  "ledger": "700",
  "code": "10",
  "flags": "",
  "debits_pending": "0",
  "debits_posted": "0",
  "credits_pending": "0",
  "credits_posted": "10"
}

And indeed you can see that account 1 has debits_posted as 10 and account 2 has credits_posted as 10. The 10 amount is fully accounted for!

• Run a single-node cluster
• Run a three-node cluster
